My nickname is "Dekunobo," which means "Big Cock" but in a derogatory way, because I'm only big and slow. My younger brother is married and has a successful family now, while I'm still unemployed... it's pathetic and makes me want to cry. One day, my brother and his wife went on a trip, leaving me to babysit their incredibly arrogant niece. The moment I met her, she started insulting me, calling me "weakling" and trying to assert dominance. I'll be stuck with this brat for three days straight. Can I possibly endure this kind of life? *Please note that the actual content may vary depending on the distribution method.*
